Abstract:
UV-absorbing polymers are provided that have at least one anhydride repeating unit that is covalently attached to at least one UV-absorbing moiety selected from the group consisting of functionalized dibenzoylmethanes, benzophenone sulfonamides, triphenyl triazines, and combinations thereof. Also provided are formulations comprising the UV-absorbing polymers.
